IMPROVEMENT IN MACHILNIES FOR SQUEEZING PUDDLERS BALLS.

. Specification forming part'of Letters Patent No. 190,385, dated May 1,1871 application filed 7 February 12,1877. 1

Buffalo, in the county of Erie and State of New York, haveinventedcertainnew and useful Improvements on Squeezers and Ido herebydeclare that thefollowingdescription of my said inventiomtaken inconnection with the accompanying sheet of drawings, orms a full, clear,and exact specification,,.w'hich will enable others skilled in the artto which it appertains to make and use the same.

This invention relates generally to puddlers 'balhs queezers; and itconsists in the combination, with a suitable frame, of three or morero1lers, so arranged that the space bounded by and includedbetween saidrollers shall be tapering or decreasing in size, twoormore said rollersbeing provided with spiral projections, whose: pitch on each rollershall berarying in relation to that of the remaining roll- .ers, wherebya puddlers ball, introduced into the larger space between said rollers,shall be caused to move forward longitudin ally through said space insuch manner that said movement will be a compound rotary, andrectilinear one at the commencement of the action upon said ball, and asthe said ball elongates and assumes the shape of a bloomla rotary andforward movement only, all as hereinafter more fnllyset forth anddescribed.

In the drawings, Figure l. is a longitudinal sectional elevation. Fig. 2is a front, and Fig. 3 a rear, elevation.

Like letters of reference indicate corresponding parts in all thefigures. v v

A A A are a series of rolls, made of suitable material, which maybehardened by any of the'well-known processes, if desired. These rolls arerevolved within suitable bearings in' aframe composed of two standards,BB. They are made tapering and hollow, and all, or at least two of them,have on their periphery spiral projections. They are, furthermore,arranged with their axial lines parallel, and with their larger endsopposite each other, so that the space bounded by and included betweenthe adjacent portions of their periphery gradually diminish in size asthat of therolls increase. The two lower rollers, A A, rotate in fixedbearings placed the propervdistance apart, while the upper one isadjustably ar motor, &c., .in the usual manner.

to the front standard B is a scoop-like receiviai ea in sliding boxesa,loc'ated in the upper part of the standards B .B,'and;they are rotatedfrom the main shaft Othrough the main spur-wheel D, intermediategear-wheel E, and the wheels D D E, respectively, the

latter'three being those secured to said rollers.-. g By-theirconnection in the manner described the rollers A A A f are all rotatedlUtfllB same direction.

. Below these rollers is located supplemental'roller, F, having anexternal contour corresponding to that of the former, except that it isshorter than those, and locatedwith its larger'end opposite the smallerend thereof. This auxiliary roller is revolved by means of thegear-wheel G fromthe gear-wheel Gr! iixed to the main shaft '0, arrangedbe1ow.said;roller F, and receives its motion from any prime Attached er,H, placed to coincide with a corresponding openingyl, in said standard,The rear standardvB has a similar opening, I, of less diameter than theformer, and likewise a correspondingly-reduced discharge-spout, H.Between the rollers A and A and A and A, respectively, are placedshields K, attached with one end to the front standardB. Y e The partsheretofore described are all made of suitable material, and of theproper 8'01 cu gth requisite ina machineof this kind. In operation theaction of the same is as follows: 4

' The puddlers ball, as it comes from the 'furnace, is placed into thereceiver H, from revolve in adirection with the said rollers,

and, in the commencement of the action of the same, in a direction atright angles thereto,

which movement results in a compound rotary motion of said ball. Thisresult is produced by the helical projections of one or more of saidrollers differing in pitch from those of theremaining rollers, or byrevolving the same faster, or bya combination of both varying pitch andaccelerated speed. In this manner the ball is first perfectly squeezedfrom all sides and afterward compressed and stretched, and it emerges,from the delivery end of the machine through the opening I in a perfectcondition as a round muck-bar.

It will be observed that the rollers are. made tapering, and have theiraxial lines all paral-' lel. This may be varied by making the rollersparallel and their axial lines converging, which would produce the sameresult ofmaking the space between the adjacent portions of the rollerstapering, and would, therefore, be a mechanical equivalent of thearrange ment heretofore described. The revolution of the ball in adirection with that of the rollers is, caused by frictionalcontact'therewith, in combination with the notches z in the-spirals, theforward move-' ment thereof by the spiral pr jections,-aud therevolution at right angles to the plane of the rollers by the varyingpitch of said spirals It'is therefore evident that, for simply revolvingthe ball in a direction .with the rollers, plain orlongitudinally-grooved rollers would'answer this purpose perfectly well;but to insure the compound forward move ment and rotary motion, at leastone of .the rollers should be spirally grooved; and to produce thecompound. rotary and rectilinear motion, two rollers,'at least, must bespirally grooved, and one of these must have spirals of greater pitchthan the remaining one. For this reason it is obvious that, while alftherollers may be spirally grooved, it is not absolutely necessary thatthey should be so constructed, but that one may be a plain orlongitudinally grooved, and the remaining two spirally grooved, andtheir pitch made to vary in any one of the manners hereinbeforedescribed. It is furthermore obvious that the diameters of the rollersmay be varying with. out interfering with their action. r l In order todeeply indent the ball when first introduced, and in a nearlyliquidvstate, and to knead the same thoroughly, and also to assist in therevolving of the ball, and to prevent it from separating on accountof'the shifting action of the spirals, these are made of V shape, withtheir forward or leading side very steep, or nearly at right angles tothe plane of the rollers, and on the forward end very high, so as toembed themselves sufficiently into the pliable mass of iron to insureits'being properly worked. For this reason, also, one of the rollers isprovided with scores or notches in the spirals, as shownin 'Fig. 2, intowhich the soft metal forces-its way, forming, as it were, projections,which act, in conjunction with said scores or depressions, in a mannersimilar to that of cog-wheels, thereby aiding in revolving said ball;but since the ball while advancing becomes more solidified, andtherefore capable of better withstanding such action, these scores ornotches, as well as the spirals, are made shallower and closertogetherfso as not to feed the bloom too fast, and not to leave markstherein'when it leaves the machine.

To compel parts of the ball detached during the squeezing and kneadingprocess should such take pla'ce notwithstanding the precautionarymeasures taken in the peculiar construction and shape of the spirals-toreunite, I have located the lowerroller F'in its indicated position, toprevent the detached parts from falling through, and thereby enablingthe'mto attach themselves again to the bulk of iron, which, at thatstage of the process, is still at a welding-heat, and also to assist inthe revolution of the ball, while the sides between the middle andupper-rollers are protected :by shields K to prevent their escapethrough the space covered bythese shields. v i

c To enable the proper criping of the rollers on varying sized balls, Ihave made the. up-' per one self-adjusting bymeans of thesliding boxesam said frame- The forward-end of this roller :is allowedto rise andfall freely, and ofitsown,accord,-'so as to adapt itself to the varying;contour of the ball, a lever, N, and connecting-rods? being providedto'lift that endjtbrf a; freeintroduotion of the ball,- But the.rear'endof thisroller should, preferably, be adjusted by means ofthescrew B, so as to produce muck-barsof uniformdiameter, thedifference-in size of the balls evidencingitself in their length. 3 v

Tokeep the rollers cool during operation, I makethem hollow, andintroduce a current of water throughth'e trunnions or bearings thereofby means ofv the pipes S. -To stren gth= on them they are internallyprovided with ra:

dial ribs, as shown in Fig. 7

Instead of the connecting-gearing an end less chain "may be employed torevolve the rollers. p 4 a The position in which the machine isoperatedis that wherein-the axes of the rollers are horizontal but it may alsobe operated in any other position. Q It isobvious that the frames B Bmust be properly braced by the tie-rods T, as shown in Fig. 2,andadditionally strengthened by bands V, made of wrought-iron, andproperly secured to said standards. Having thus fully described myinvention, Iclaim V v 1.
